Locking system for shipping container including bolt seal and electronic device with arms for receiving bolt seal

Abstract

An electronic locking device secures a shipping container and includes a housing, two arms, a sensing circuit, and electronics. The pair of arms extend from the housing and couple to the hasp. The arms transition between locked and unlocked configurations relative to the hasp, with one or both of the arms pivoting relative to the other. A bolt seal locks the arms in the locked configuration. The sensing circuit, which includes sensing contacts, is in a “closed” state or “open” state depending on whether the arms are in the locked or unlocked configuration. The electronics record and report the state of the sensing circuit, thereby indicating whether the arms are locked or unlocked.

Benefits of technology

[0011]In a feature of this aspect of the invention, the housing further includes a support carriage and a barrier to prevent access to the electronics enclosure from the support carriage. In another feature, the electronics record the state of the sensing circuit. In a further feature, the electronics record the state of the sensing circuit in computer-readable medium that is contained in the electronics compartment. In still another feature, the electronics report the state of the sensing circuit. In a further feature still, the electronics report the state of the sensing circuit through wireless communications. In an additional feature, the housing comprises a rugged mechanical housing. In yet another feature, the arms are configured to concurrently receive a bolt therethrough when in the locked configuration. In another feature, a bolt of a bolt seal extends through a respective opening in each of the

Problems solved by technology

Although there is an ISO standard for these bolts, they are not necessarily identical from one manufacturer to another.

Although far from fool proof, the technique does provide a simple method of keeping the doors on shipping contain
